Mikel Olazaran's 1993 sociological history of the Perceptrons controversy lists both the 1969 and 1988 editions of Perceptrons alongside Robert Merton's priority/multiple-discovery corpus in one bibliography

Mikel Olazaran's "A Sociological History of the Neural Network Controversy" (1993) — already the vault's primary source for its "social closure, not scientific refutation" reading of the Minsky–Papert–Rosenblatt dispute (see claim-sri-retooling-predates-published-perceptrons-refutation, observation-dreyfus-olazaran-converge-connectionism-eclipse-was-social) — turns out, in its own reference list, to hold both halves of an otherwise unconnected pair of vault clusters. Olazaran's bibliography lists both editions of the book at the center of the vault's Perceptrons-availability thread:

"Minsky, M. L., and Papert, S. A. (1969). 'Perceptrons: An Introduction to Computational Geometry.' The MIT Press: Cambridge, Massachusetts."

"Minsky, M. L., and Papert, S. A. (1988). 'Perceptrons: An Introduction to Computational Geometry.' (expanded ed.). The MIT Press: Cambridge, Massachusetts."

— and, separately, two works from Robert K. Merton's priority/multiple-discovery corpus, the same scholarly tradition behind the vault's Merton-1957 cluster:

"Merton, R. K. (1961). Singletons and multiples in science."

"Merton, R. K. (1973). 'The Sociology of Science: Theoretical and Empirical Investigations.'"

The contact is citational and sits at the level of the document's apparatus, not (yet) its argument: nothing follows automatically from two subjects sharing a bibliography. But it is a directly-read, Tier 1 fact about the document — the single primary the vault already leans on for the Perceptrons-controversy story independently names Merton's priority sociology in the same reference list, a fact that exists regardless of what any retrieval tool's cosine score says about the two subjects' prose. See claim-olazaran-1993-applies-merton-multiple-discovery-to-werbos-not-perceptrons-dispute for what, if anything, that citation is actually used for inside the chapter.
